Product Watch: DeWalt Infrared Thermometer

Even if you're not an hvac guy troubleshooting a heating system, a noncontact infrared thermometer is a useful item to have in your toolbox. The DeWalt Thermometer, powered by the company's new 12-volt MAX series battery, can be used for locating insulation problems and air leaks and for checking motors, electrical components, and anywhere else that temperature matters. Its most interesting feature is the LED, which glows red or blue to indicate temperature changes as the laser moves across a surface. The thermometer measures temperatures from -20° F all the way up to 932° F.¦ Price: $150. 800-433-9258. www.dewalt.com.
